TheDeadline is a simple but effective task management system that uses easy to remember shorthand and keyboard shortcuts for speedy task entry. When you create tasks you can assign ownership to your friends or coworkers with a simple @ designation and can categorize tasks with # hash tags—just like Twitter. You can also share tasks with groups you've created by using the &groups tag. TheDeadline also integrates with Google for easy task sharing among your contacts and integration with your Google Calendar.
